As shown in figure 1, the application relates to an automatic cleaning device for a wind box cover of a wheat harvester, which mainly comprises a U-shaped brush plate 15, a sliding guide rail, a speed reducing motor 12, a small belt wheel 22, a large belt wheel 25, a belt 24, a fixed support, a base 1, a connecting rod, a traction frame 11 and a universal joint 23. The speed reducing motor is arranged on the fixed support 9 through bolts and nuts, the output shaft of the motor is connected with a universal joint 23, and a universal joint shaft 13 is connected with the small belt wheel 22 through a bearing so as to drive the small belt wheel 22 to rotate. As shown in fig. 2, the small pulley rotates a large pulley 25 via a belt 24, and a bearing is installed in the bearing housing 14. The driving shaft 7 is connected with a large belt wheel 25 through a bearing, and the bearing is arranged in a bearing seat. The first connecting rod 6 is rigidly connected with the driving shaft 7, the first connecting rod is rigidly connected with the second connecting rod 5, the second connecting rod is hinged with the third connecting rod 4, and the third connecting rod is hinged with the traction frame 11. The big belt wheel drives the first connecting rod to do circular motion through the driving shaft 7, the first connecting rod drives the second connecting rod to rotate, and the traction frame is driven by the third connecting rod to drive the U-shaped brush plate to do reciprocating motion on the sliding guide rail, so that the bellows cover can be automatically cleaned.

The small belt wheel 22, the large belt wheel 25 and the belt 24 are transmission parts and are in modular design, and the specifications of the small belt wheel, the large belt wheel and the belt can be selected according to specific working environment and technical requirements.

Specifically, the two U-shaped brush plates 15 are connected and positioned by two connecting plates 16 in a welding manner, the U-shaped brush plates are mounted on a sliding block 18 of the sliding guide rail by screws 17, the inner sides of the U-shaped brush plates 15 are provided with the soft brushes, the installation manner of the soft brushes can be industrial glue adhesion or iron wire binding, and the specific installation manner can be determined according to the installation environment. The traction frame 11 is connected with the U-shaped brush plate in a welding mode. Because the top plane of the grain bin of the harvester and the bottom plane of the air box are positioned at different heights, the plane of the base plate 1 and the plane of the sliding guide rail are positioned in two different parallel mounting planes. The bottom plate 1 is installed on a granary of the wheat harvester through screws, and the base 21 of the sliding guide rail is installed at the bottom of a wind box cover of the wheat harvester through screws. The speed reducing motor 12 provides driving force for the whole device, the wheat harvester is started when the wheat harvester starts to work, and the wheat harvester is closed when the wheat harvester stops working. The speed reducing motor fixing support 9 and the small belt wheel fixing support 10 are formed by vertically welding two iron plates and are respectively welded on the bottom plate 1.

As shown in figure 3, the installation diagram of the device of the invention is simplified, and the granary, the air box and the harvester body are all processed.

Specifically, the motion principle of the device is the motion principle of a concentric crank-slider mechanism, the prime mover is composed of a first connecting rod 6 and a second connecting rod 5, the connecting rod is a third connecting rod 4, and the slider is composed of a traction frame 11 and a U-shaped brush plate 15. As shown in figure 1, the first connecting rod is positioned at the leftmost position, the speed reducing motor is started at the leftmost position, the first connecting rod starts to rotate from the leftmost position, the first connecting rod starts to rotate for a circle from the leftmost position, and at the moment, the U-shaped brush plate just completes one reciprocating motion on the sliding guide rail, so that two times of cleaning of the bellows cover are realized. The length of said first link 6 is equal to half the length of the sliding guide, so that the U-shaped brush plate moves to the leftmost side when the first link moves to the leftmost side and to the rightmost side when the first link moves to the rightmost side, so as to achieve the complete cleaning of the bellows housing. The length of the traction frame 11 in the direction of the sliding guide rail is slightly longer than the length of the first link, so that no interference occurs when the first link moves to the leftmost position, so as to ensure a complete movement path.

The purpose of automatically cleaning the air box cover in the wheat harvesting process can be achieved through the process, the defects of manual cleaning are effectively overcome, time and labor are better saved, and the working efficiency is greatly improved.
